Gamma-Secretase Inhibitor RO4929097 and Gemcitabine Hydrochloride in Treating Patients With Advanced Solid Tumors

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This phase I trial is studying the side effects and best dose of gamma-secretase inhibitor RO4929097 when given together with gemcitabine hydrochloride in treating patients with advanced solid tumors. Gamma-secretase inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving gamma-secretase inhibitor RO4929097 together with gemcitabine hydrochloride may kill more tumor cells.
